A display device of a vehicle on which a CO.sub.2 recovery device is mounted, the CO.sub.2 recovery device through which gas circulates recovering carbon dioxide from the gas, the display device includes: a controller configured to control the vehicle, the controller including a recovery state determination unit configured to determine a recovery amount or a recovery state of the carbon dioxide recovered by the CO.sub.2 recovery device and an image data creation unit configured to create image data corresponding to the recovery amount or the recovery state detected by the recovery state determination unit; and a display screen configured to receive the image data and display an image corresponding to the image data, wherein the image data and the image vary depending on the recovery amount or the recovery state.

Described are gas-processing systems that include a pre-heater, that are useful for processing a flow of gas flowing the gas to contact media (e.g., purification media, catalyst, adsorbent), and related methods.

A method and system for an enhanced reforming process employing a pressure swing absorber. An off-gas from the pressure swing absorber is divided with a first portion sent back into a reforming reactor and a second portion sent to a heat generator for the reforming process. The first off-gas portion from the pressure swing absorber can be pressurized by a compressor and reintroduced into a fluidized bed reactor.

A method for capturing CO.sub.2 from a gas stream using a metal organic framework (MOF) based physisorbent CO.sub.2 concentrator is provided. In the method, MOF material is pretreated, a gas stream is then introduced into the CO.sub.2 concentrator which comprises the pretreated MOF material. CO.sub.2 from the gas stream is captured with the CO.sub.2 concentrator to generate a CO.sub.2-free stream, which is discharged the from the CO.sub.2 concentrator into the atmosphere. Introduction of the gas stream into the CO.sub.2 concentrator is stopped when the pretreated MOF material becomes saturated with CO.sub.2. The CO.sub.2 concentrator with the saturated MOF material is then regenerated by introducing hot air, hot nitrogen, vacuum, or a combination thereof into the CO.sub.2 concentrator thereby generating a CO.sub.2-rich stream. The CO.sub.2-rich stream is diverted for purification and the regenerated CO.sub.2 concentrator is recycled for future capture of CO.sub.2.

A sensor system comprising a housing having an inlet aperture through which fluid enters the housing and a conditioning material in the housing, the conditioning material being adapted to control levels of a substance within the housing. The sensor system comprises a sensor for analysing the fluid in the housing. The sensor system comprises circulation means which is configured to alternate circulation of fluid within the housing between a sensing fluid path in which the fluid is analysed by the sensor and a second fluid path in which the fluid flow is conditioned. A method for analysing fluid in a housing using a sensor is also provided.

The apparatus for producing liquid water from ambient air includes a lower frame and an upper cover defining an inner space, and at least one air inlet in the lower frame. An adsorption and desorption module is arranged in the inner space with a bed of adsorbent material. A ventilator varies between a first mode in which it imposes vertical forced circulation of the ambient air, and a second mode in which the upper cover acts as a condenser for the ambient air. A valve is arranged in the upper cover to allow the ambient air to flow from the inner space to the outside environment when the ventilator is in the first mode, the valve being otherwise closed. An electronic unit switches the ventilator selectively into the first mode during a period of night time and into the second mode during a period of day time.

The present invention is directed to a method, device and system to capture carbon dioxide in air using solid amine sorbents and using a radio frequency and/or microwave generator to desorb the carbon dioxide by directly exciting the amine-carbon bond thereby significantly reducing the energy cost of releasing the carbon dioxide.

Disclosed are a disease diagnosis device and a diagnosis method thereof. The disease diagnosis device includes a pump for pumping a respiratory gas, a first pre-treatment portion connected to the pump and removing moisture and bad breath in the respiratory gas, and a volatile organic compound (VOC) detection portion connected between the first pre-treatment portion and the pump to detect VOCs in the respiratory gas.

Fiber compositions are provided that incorporate metal organic framework (MOF) materials into the polymeric matrix of the fiber. The metal organic framework materials can be incorporated by including MOF particles into a “dope” or synthesis solution used to form the fiber. The dope solution can then be used to form fibers that include 5.0 wt % or more of MOF in the resulting polymeric structural material of the fiber, relative to a weight of the fibers. In some aspects, the metal organic framework material can correspond to a MOF with selectivity for adsorption of CO.sub.2.

Contactor structures are provided that can allow for improved heat management while reducing or minimizing the potential for contamination of process gas streams with heat transfer fluids. The contactor structures can include one or more sets of flow channels for process gas flows, such as gas flows introduced to allow adsorption of components from a gas stream or gas flows introduced to facilitate desorption of previously adsorbed components into a purge gas stream. The process gas flow channels can correspond to flow channels defined by a structural material of unitary structure. The unitary structure can correspond to the entire contactor, or the unitary structure can correspond to a monolith that forms a portion of the contactor. The contactor structures can also include one or more sets of flow channels for heat transfer fluids. The heat transfer flow channels can also be defined by the structural material of a unitary structure.
